Interesting, I assume that by installing the hombrew channel you'll be messing with iOS stuff?
I have a pal wiiu and I have some GC games that I would like to play. I also have brawl that I can use for the hbc, but I'm a bit hesitant on doing it.Still, whats the best guide for this, do I really need a max sized 2GB SD card?Also, I've read some pple here using the USB loader gx with nintedon't, how does this work?
1. nope. you only need to mess with IOS's if you are using certain Wii USB loaders. The Homebrew Channel and Nintendont require no modification of IOS's at all.
2. the best source is in the OP. and yes, you need a 2gb or under SD card or micro SD in adapter as Brawl does not recognize anything above that. For everything else, you can use any size.
3. USB loader GX should just recognize it automatically. Did for me, but I may be wrong. I don't use it, so I'm not the best person to ask about that.
